 !!!!!!!!!!!!!!!!!!!!!!!!!!!! IMPORTANT NOTE !!!!!!!!!!!!!!!!!!!!!!!!!!!!
 ! The default datasets used to produce the HGT_M, GREENFRAC, 
 ! and LU_INDEX/LANDUSEF fields have changed in WPS v3.8. The HGT_M field
 ! is now interpolated from 30-arc-second USGS GMTED2010, the GREENFRAC 
 ! field is interpolated from MODIS FPAR, and the LU_INDEX/LANDUSEF fields 
 ! are interpolated from 21-class MODIS.
 !
 ! To match the output given by the default namelist.wps in WPS v3.7.1, 
 ! the following setting for geog_data_res may be used:
 !
 ! geog_data_res = 'gtopo_10m+usgs_10m+nesdis_greenfrac+10m','gtopo_2m+usgs_2m+nesdis_greenfrac+2m',

Hay que tener cuidado cuando se hace link a la carpeta entera, porqu si hay otros archivos ademas de los grib los lincara como GRIB.

Ejemplo clasico es que ne la misma carpeta estan los archivos para bajar la meteorología

En ese caso hay que mover los archivos que no son grib2 a otro lugaqr y ahi linkear la carpeta
